Bucket Wheel Excavators cutting up to 50 MPa

The thyssenkrupp Industrial Solutions business area has introduced a new generation of compact bucket wheel excavators: the “Barracuda” and the “Mine Shark”. Both machines will be able to work in hard materials with compressive strengths up to 50 MPa.

Newly developed bucket and tooth designs enable the machines to work in a wide range of materials.

While bucket wheel excavators today mostly work in soft and medium-hard rock with an uniaxial compressive strength (UCS) of up to 20 MPa, the newly designed type of equipment is capable of working in a broad range of materials including coal, limestone, phosphate rock, potash, frozen materials in winter conditions as well as in its corresponding overburden layers.

In order to fulfill the requirements of the severe working conditions, special bucket and tooth designs have been applied by thyssenkrupp Industrial Solutions. These designs are based on innovative testing methods and include a larger number of teeth and buckets. This stage of development of bucket wheel excavators demonstrates the changing character of the extraction process from digging to cutting.

The combined extracting and loading process within a single machine eliminates hazardous and ecologically harmful blasting as well as additional loading activities. That is why health and safety standards at highest level can be ensured. Considering the fact that the new bucket wheel excavators are able to produce throughputs of over 3,000 tph, whereas less number of vehicles and manpower are required, the operational expenditures can be reduced significantly.
